nano aquarium siphon

I have the small and the larger versions and I use them all the time. The big one is great for my 90 gallon to reach the bottom. I use it to clean up small spots or deposit shrimp food in to their little shrimp cave. I can suck up loose algae or medium size dead bladder snails. I also use it to feed frozen foods like blood worms. Before the frozen cube would hit the tank current and explode into a rapidly scattering worm cloud. Most would go to waste and make a huge mess of the tank. Now, I melt them in tank water and suck them up in this. I can provide small controled puffs of wormy deliciousness that they quickly gobble up! The little buggers can see the worms inside, so the try to bite the tube. Apparently the love of blood worms trumps the suspicion/fear of all foreign things entering their crib. The little interference fit collar for the 90-degree extension is a little hokey and won't let me push bigger things around on the bottom of my tank, but overall it works very well for me.

I use this for both my fresh water and saltwater aquariums. It has great suction to ot and I really enjoy the attachment that comes with it since it allows be to reach under things without moving them or disturbing things to much. I mainly use this for waste, extra food or sediment removal that builds up in my tank. It's a lot sturdier around the rubber ring then others I've owned, very easy to clean and the size is percent for any aquarium 40 gallons and below.

I use this all the time now in my 29gal aquarium. It can reach the substrate quite easily. I can use it to clean up detritus, suck up snails, blow junk off leaves, etc. Very useful and it holds together well. I don't usually need the extension tube but it could be useful in certain situations. The extension does feel like it will start slipping off the end after a while, since it kind of stretches every time you attach it.

Bought this because I have a small 5 gallon tank I use for plecos. My tank is on a lower shelf of my 30 gallon tank stand so a normal gravel cleaner would not work. This syphon worked perfectly. I also like that it came with an angled attachment to use for feeding small fish.

Was exactly as described and good quality. Perfect

Works, but balloon is small and stiff. Should be larger and softer rubber for better performance and control

But this specifically to clean up the substrate in my planted aquarium from algae and detritus, comes with a special little tube for feeding that really targets where you need the food

I use this to make sure everyone in my tank gets their dinner! I have some greedy little dojo loaches and some ravenous neon tetras. If I dump food on top of the water, they suck it up like they'll never be fed again. They're crazy. I use this to make sure my sweet little pygmy corys get their fair share. It's a simple design and it has held up to daily use for months. Can't complain!

All plastic. Tip doesn't go on well

Works good does the job, However I wish the tip was a bit more flexible, but overall, good!!
